Continuous and Prime Power Ratings

Understanding generator ratings is important when selecting an auxiliary marine power system.

The Nanni QMS16M provides:

The continuous rating is generally the more relevant figure when evaluating the vessel’s normal sustained electrical demand. The prime-power rating represents the generator’s published operating capacity under the applicable duty conditions.

The vessel’s expected electrical load should remain within the generator’s approved operating range while leaving reasonable reserve capacity for temporary increases in demand.

Equipment such as marine air-conditioning compressors, refrigeration systems, pumps, battery chargers, water makers, and electric motors may require considerably more electrical power during startup than during normal operation.

Selecting a generator that is too small may result in:

• Electrical overload
• Voltage instability
• Difficulty starting compressors or motors
• Excessive operating temperatures
• Frequent protective shutdowns
• Reduced generator service life

However, selecting a generator that is substantially larger than required may result in prolonged operation under very light load. A professional marine electrical load assessment helps balance generator capacity, equipment startup demand, operating reserve, fuel efficiency, and long-term engine performance.

• Domestic onboard equipment

Before installation, a qualified marine electrician should verify:

• Generator voltage
• Electrical frequency
• Cable sizes
• Earthing and bonding arrangements
• Circuit protection
• Switchboard compatibility
• Shore-power integration
• Load distribution

Stable onboard electricity depends on the complete installation rather than the generator alone. Engine-speed stability, alternator regulation, cable sizing, grounding, circuit protection, and load management all influence electrical performance.

Professional installation and commissioning are therefore important for safe and dependable long-term operation.
